The solidification processes of titanium (TiO2) nanofluids and deionized water (DW) were measured by differential scanning calorimetry to explore the effect of sodium dodecylsulfate (SDS) surfactants on the supercooling degree of TiO2 nanofluids. The supercooling degrees of TiO2 nanofluids...

Solar air heaters are becoming more and more popular in space heating and industrial processes due to their cost effectiveness and easy maintenance. However, how to increase thermal efficiency of solar air heaters becomes a major challenge. In this paper, the design of a solar air heater with...

Graphene is widely utilized because of its exceptional properties, such as strong mechanical strength, low weight, nearly optical transparency, and excellent conductivity of heat and electricity. In this study, we used the ultrahigh specific surface area of graphene due to its inherently...
